I want to ask question from a newbie 🙂. Should I use Appollo-Server 2 or GraphQL-Yoga and the best to use alongside with prisma?

They’re pretty identical but you’ll still find Yoga takes care of a few things for you. Importing schema files for one is already wired up. I’d have a look at Apollo Server with Nexus and the new yoga2 repo. Some good ideas there starting with the code first approach.
